Dutch architects to print out a house, piece by piece

A 3D printer -- nearly 20 feet tall -- will be turning out components on site for the first 3D-printed house, to be finished by year's end in the Netherlands, according to the printer's developer, DUS Architects. DUS says the technology affords the opportunity for a "new craftsmanship" that allows custom production "that involves both the physical world and the virtual world." The KamerMaker printer uses polypropylene, but it is hoped the machine can eventually employ recycled plastic.
